One of the arrested was Adam Cranston, son of Michael Cranston, who was charged with conspiracy to defraud the Commonwealth.

In a press conference last month, AFP Deputy Commissioner Leanne Close confirmed that three ATO officials, including Mr Cranston, were being investigated in relation to the case.

“A senior official from the Australian Taxation Office has been issued with a court attendance notice where we’re alleging that he has abused his position as a public officer and senior official of the Commonwealth,” Ms Close said.
